Specification of Letters Patent.

Patented Sept. 19, 1905.

Application filed January 13, 1905. 9 Serial No. 240,951.

To allwhom it may concern:

Be it known that 1, JOHN A. BRYANT, a citi-' zen of the United States,residing at Pine Village, in the county of Warren and State of Indiana,have invented a new and useful Tire Bolting Machine, of which thefollowing is a specification.

This invention relates to machines for applying nuts to bolts andholding the bolts while the nuts are being applied, and has for itsobject to produce a simply-constructed device of this class efficient inaction, easily operated, and adapted for adjustment to various sizes ofnuts and bolts.

With these and other objects in view, which will appear as the nature'ofthe invention is better understood, the same consists in certain novelfeatures of construction, as hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, andin which corresponding parts are denoted by like designating characters,is illustrated the preferred form of embodiment of the invention capableof carrying the same into practical operation, it being understood thatthe invention is not necessarily limited thereto, as various changes inthe shape, proportions, and general assemblage of the parts may beresorted to without departing from the principle of the invention orsacrificing any of its advantages.

In the drawings thus employed, Figure 1 is a side elevation, and Fig. 2is a plan view, of theimproved machine. Fig. 3 is a transverse section,enlarged, on the line 3 3 of Fig. 1. Fig. 1 is a plan view, enlarged, ofthe head portion of the bolt-severing shears. Fig. 5 is a perspectiveview of the operative end of the nut-feeding shuttle. Fig. 6 is a planview of the rear end of the bed-frame and of the nut-holding magazine.Fig. 7 is a longitudinal sectional view, enlarged, of the head end ofthe machine. Fig. 8 is a transverse section on the line 8 8 of Fig. 7,illustrating the construction and operation of the bolt-clippingmechanism. Figs. 9 and 10 are detailviews illustrating the constructionand action of the shuttle-operating mechanism. Fig. 11 is a view similarto Fig. 1, illustrating some modified features of the construction. Fig.12 is an enlarged detail perspective view of a portion of thenut-feeding mechanism. Fig. 13 is an enlarged perspective view of thefollower member.

The improved device is designed more particularly for setting the nutsupon the tirebolts of vehiclewheels, and is shown applied to a machineemployed for this purpose for illustration, but is not necessarilylimited thereto, as will be obvious. The construction thus employed forillustrating the embodiment of the invention comprises a bed-frame 10 ofsuitable size, mounted upon legs 11. At one end of the frame 10 a headmember is connected comprising spaced standards 12, 13, 14:, and 15 andcarrying an operatingshaft 16. provided with a crank 17 for rotating thesame. Mounted for longitudinal movement in the standards l t 15 is a rod18, operative by a lever 19, pivoted at 20 to a bracket 21, extendingfrom the standard 15 and provided with a spring 22 to maintain the rodyieldably in withdrawn position. The rod 18 is designed to be pressed bythe movement of the lever 19 against the head of the bolt to hold thesame stationary while the nut is being applied thereto, a section ofvehicle-felly 35, tire 36, and a tire-bolt 37 being shown in Fig. 7 toillustrate the operation. Mounted for rotation in the standards 12 13 isa sleeve 23-and carrying a gear-pinion 24: exteriorly' thereof and witha square interior for receiving the, nut-socket 25. The shaft 16 is pro-,vided with a gear-Wheel 26, engaging with the pinion 24, so that therotation of the shaft will also rotate the sleeve 23 and .socket 25. Theinterior of the socket corresponds to the nut to be applied to the boltand is easily detachable to permit sockets of different sizes fordifferent sizes of nuts to be attached to the machine. Attached to theouter face of the standard 12 is a guideway 27, conforming interiorly tothe nutsand terminating at the lower end upon a plate 28, extendinglongitudinally of the frame 10 and with the upper .end of the guidewayopposite the intake end they are opposite the entrance to the socket thepin 34 to enter the threaded aperture in the nut, and the inner end ofthe needle member will then bear upon the'nut and thrust it into thesocket and against the inner end of the bolt 37 for threading upon thesame, as hereinafter explained. The needle-standard 31 is adjustablelongitudinally of the arm 30, as by clamp-nuts 91, to provide for anyrequired adjustment, and the guideway 27 is provided with anadjusting-screw 92 in its upper end. to control the upward position ofthe nut which is elevated by the shuttle. Thus by means of theadjusting-bolt 92 the limit of the upward movement of the nuts will becontrolled, so that the threaded aperture of the same will be disposedexactly opposite the center of the socket 25, no matter what the size ofthe socket or nut may be, or, in other words, the adjusting-screw 92provides for adapting. the device for the various sizes of nuts or forslight variations in the sizes of the same grade of nut.

The adjusting members 91 provide means for the vertical adjustment ofthe standard 31, so that the needle members 33 34 may be maintained inproper alinement relative to the socket 25, as will be obvious.

Attached to the bed-plate 28 are L-shaped members 38 39, forming amagazine or guide for the nuts and terminating at the entrance to theguideway 27, so that the nuts will be fed thereto consecutively.

The nuts (represented at 40) are first placed upon a wire core 41, andthe plurality of nuts thus arranged, together with the wire core, placedin the magazine, with the outer end of the wire attached to a stop-plate43 to prevent longitudinal movement to the wire, care being taken thatthe free end of the wire shall stop short of the entrance to theguideway 27, so that the last nut shall be free of the wire core. Afollower 42 is then placed upon the core-wire in the rear of the seriesof nuts, the follower havinga longitudinal opening 93 to permit it to beso placed and also provided with an eye 45. A cable 44 is connected byone end to the eye 45 of the follower and carried thence over guidepulleys 46 47 to a weight 48 to provide a tension to the nuts andmaintain them pressed against the lower end of the guideway to keep thelast nut of the series at all times in proper position to be acted uponby the feeding mechanism.

The nut-feeding mechanism consists of a shuttle 49, mounted for movementvertically through the frame 10 and into the guideway 27 and providedwith spaced resilient arms 50 51, having inwardly-extending shoulders 5253 near their free ends. The space between the arms 50 51 is justsufficient to receive the nuts 40 one at a time as the shuttle isoperated. The shuttle member is thinner than the nuts 40 and movesupward and downward past the inner end of the plate 28, the latterformed with a tongue 107,extending into the space between the resilientarms 50 51 and narrow enough to permit the shoulders 52 53 to pass it atthe downstroke of the plunger, the tongue extending downwardly. as shownat 108, far enough to prevent the shoulders from passing beneath thetongue. Thus as the shuttle is moved upward the shoulders 52 53 pick upthe last or inner nut of the series and carry it upward into positionopposite the socket 25, and as soon as the shoulders 52 53 pass abovethe series of nuts the pressure created by the weight 48 will thrust thenext nut into position within the guideway' 27 and between the resilientarms 50 51. After the needle member 33 has acted and removed the nutwhich has been supported by the shoulders 52 53 the shuttle is returnedto its downward position, and as the inclined lower faces of theshoulders reach the nut which has been thrust forward to replace the onejust elevated the resilient arms will yield laterally and the shoulderswill pass by the nut and take position beneath it ready for the nextaction. Thus one nut will be picked off and elevated to positionopposite the socket 25 at each stroke of the shuttle. The lower end ofthe shuttle is guided by a bracket 54, attached to the frame 10 andsuitably braced, as at 55. The mechanism shown for operating the shuttleconsists of a bar 56, mounted for longitudinal movement through keepers57 58, attached, respectively, to one of the legs 11 and the bracket 54and provided upon the outer end with a lateral arm 59, against which theknee or leg of the operator may be thrust to operate the bar, or it maybe operated by a foot-treadle mechanism, as at 96 in Fig. 11, as may bepreferred. Supported for rotation, as by hangers 6O 61 from the frame10, is a shaft 62, carrying an arm 63 at one point there-- on andterminating in a stud 64, passing through an aperture in the shuttle 49,and with another and shorter arm extending for engagement by a stud 66,yieldably supported in projected position by a spring 87. the free endof the arm 65 being formed with an inclined portion 88 to assist in theaction, as hereinafter shown.

The shaft 62 is provided with a spring 67, operating to maintain thearms 63 and 65 yieldably in their downward positions, and a spring 68 isalso attached to the bar 56 to maintain the same yieldably in withdrawnposition.

Pivoted at 69 to a hanger 70, depending from the base member 10, is alever 71', one end of the lever attached to the needle member 33 and theother end extending through a relatively long loop 72 at the free end ofthe bar 56, the loop permitting a certain degree of lost motion betweenthe arm and lever, the object to be hereinafter explained.

Attached to the bed member 10 at opposite sides are guide-rods 73 74,upon which a bracket 75 is slidably disposed and provided with avertical stud 76 to provide a central support for the hub of the wheelin whose fell y and tire the bolts are to be placed. The bracket and itsstud, being adjustable upon the guide-rods, are readily adaptable to thevarious sizes of wheels to be operated on. Mounted for longitudinalmovement above the magazine for the supply of the nuts 40 is an arm 97,slidable through a guide 98, attached to the magazine member 38, andprovided with a spring 99 for maintaining the arm yieldably in projectedposition. Pivoted at 100 to the arm 97 is a lever 101, which is pivotedin turn at 102 to the member 38 and projects by its free end into thepath of a vertically-moving bar 103. The bar 103 is supported in guides104 on the frame 10 and provided with a spring 105 to maintain the sameyieldably in its downward or withdrawn position. The upper end of thebar 103 is inclined for engaging the free end of the lever 101 andswinging it laterally upon its pivot 102, and thereby throwing theyieldable bar 97 rearwardly.

Attached to the operating-bar 56 is a camrib 106, adapted to hold thebar 103 'in elevated position and maintain the arm 97 in withdrawnposition during the time the operating-bar 56is in withdrawn position,The cam-rib 106 will be so disposed that it will pass beneath the bar103 and lower it, and

thus release the member 97 just after the shuttle begins its upwardstroke, so that the member 97 will be caused to follow the outermost nutof the series into the space between the resilient arms 50 51 just assoon as the shuttle has picked off the nut which it is desired toelevate and hold the next nut from being moved by the shuttle in itsoperation. The nut, whichfor the time being is held in the shuttle belowthe shoulders 52 53, 'is thus efiectually supported and held fromjumping or displacement by the movement of the shuttle. At the returnmovement of the bar 56 the cam-rib 106 again passes beneath the bar 103and withdraws the member 97 and holds it withdrawn until the next strokeof the shuttle. Attached to the base portion of the head member is astandard 77, having a shearing-jaw 78 upon the upper end and preferablywith the shaft 16 passing through it to assist in supporting thestandard. The standard is also provided with spaced plates 79, betweenwhose free ends an arm 80 is pivoted at 81 and provided with an opposingshear-' jaw 82 for coaction with the shear-jaw 78. Pivoted at 83 in thelower end of the arm 80 is a lever-arm 84, having a lateral projection85 for bearing upon a plate 86, attached to the base member 10.Embracing the leverarm 84 is a keeper or guard 89, in which a spring isinclosed, and bearing upon the lever-arm to hold the same yieldably inits depressed or inactive position, and thus hold the jaws 78 82separated when not in use. By this arrangement it will be obvious thatthe depression of the free end of the leverthe free end of the socket25.

arm 83 will cause the projection 85, to serve as a fulcrum to the lever84 and cause the requisite action of the arm 80, and thus actuate thejaw member 81 against any object held between the opposing jaws, thewhole forming an effective shearing mechanism, whereby the surplus endsof the bolts 37 may be severed after the nuts are applied.

The magazine may be of any desired length for holding any requirednumber of the nuts.

With a machine thus constructed the operation is as follows: The wheelbeing placed upon the stud 76 and the latter adjusted to bring the folly35 and tire 36 in proper position relative to the holding member 18 andsocket 25, a bolt 37 is placed through the tire and felly and itsthreaded end inserted into The operator then moves the lever 19 to causethe holding member 18 to bear against the head of the bolt and press thefelly against the adjacent end of the socket 25. The operator thenpresses with the knee or leg upon the arm 59 or upon the treadle 96, asthe case may be, and operates the bar 56 and causes the pin 66 to engagethe arm 65 and rotate the shaft 62, and at the same time cause arm 63 toelevate the shuttle 49 and carry the nut engaged by the shoulders 5253to position opposite the entrance to the socket 25, the stop mechanism97 101 being also operated,as before described. The parts will be soproportioned and disposed that the stud 66 will reach the inclinedportion 88 of the arm 65 when the shuttlehas been elevated to itshighest point, and by that time the inclined portion will be in ahorizontal position or parallel to the line of travel of the pin 66, sothat the further movement of the pin will not move the arm 65, and thushold the shuttle stationary and in its elevated position for a time. Atthe first portion of the stroke of the bar 56 the elongated bearing 72will be moving past the lower end of the le-' ver 71, so that the needlemember 33 will be inoperative until the shuttle has fully elevated thenut. The stud 66 will have reached the outer end of the inclined portion88 just as the inner end of the bearing 72 engages the lever 71, so thatthe spring-pin 34 of the needle member 33 will pass through the aperture29 in the guideway 27 and pick up the nut just before the pin 66 passesfrom beneath the arm 65 and releases the shuttle and permits the spring67 to moveit downward into its former. position. In the meantime thecontinued movement of the bar 56 causes'the needle member to carry thenut into the socket 25 and press it against the end of the bolt 37, theyielding pin 34 when it engages the bolt withdrawing into the needlemember, leaving the latter free to be pressed against'the nut, whichwill then be rotated and turned home upon the bolt by rotating thesocket through the action of the handle. As soon as the nut is wellstarted upon the bolt the knee-operated bar can be released and thespring 68 permitted to restore the bar to its former position, thisaction likewise restoring the needle member to its outward position andthe stop member 97 to its former position. At the return movement of thebar 56 the arm will compress the spring-supported stud 66 and pass it,and the latter will be automatically returned to its former position.After the nut has been set home the lever 19 is released and the wheeltilted to bring the bolt into position between the shear-jaws 78 82 andthe lever 84 operated to sever the surplus ends of the bolt. Theoperation is then repeated for all the bolts of the wheel, and by simplyadjusting the bracket 75 and its stud 76 along the guiderods 73 74 bothsizes of the wheels of the vehicle may be operated upon with equalfacility or any other desired size operated upon, as will be obvious.

The guide members 38 39, forming the magazine for the nuts, will beadjustable laterally, as by slots 93 and 94 and clamp-bolts 95 and 96,as shown in Fig. 6, to adapt the device to different-sized nuts, so thatby providing a plurality of the guideways 27, sockets 25, and shuttles49 of different sizes for. the different sizes of nuts the same machinemay be adapted for all sizes of nuts and bolts usually employed.

While the machine is more particularly adapted for applying the nuts tovehiclewheels, the same may be applied by making slight and immaterialmodifications to various structures wherein it is desired to attach nutsto bolts, and I do not, therefore, desire to be limited in any manner inthe purposes for which the machine shall be employed.

The machine can be inexpensively manufactured and operates efficientlyfor the purposes described.
